ABSTRACT
This paper is mainly studying how to use similar formula to calculate the response of the system of the isolation building. There are five different kinds of similar formula. The process of the ratiocination of the formula is mainly using the first mode of the system to stimulate. Therefore we can directly transfer the MDOF into many SDOF. The advantage of this method is that the first mode was directly calculated by mass and stiffness matrix. It has nothing to do with the damping matrix. Therefore, it will not be like mode – superposition method, which is necessary to assume the form of damping.
According to the result of the study, in the system of isolation building, the response of the structure calculated by the second and fourth formulas are very accurate. When calculating general building, the second formula is better than the other methods. And there will be a magnifying effect when using the first and third methods, which causes a bigger error. |
